IMPROVEMENT IN FIRE-PROOF PAINTS.

S ecification forming part of Letters Patent- No. 150,562, dated May 5,1874; ap lication filed April 13, 1874.

To all whom it may concern:

Be it known that I, LLovD S. Glnsox, of Jamestown, Chautauqua county,"Sew York, have invented a Composition for Fire-Proof Paint; and I dohereby declare the following to be a full and correct description of thesame.

The object of my invention is to produce a composition for fire-proofpaint for the protection, as well as preservation, of roofs and outsidesof buildings and other objects which are exposed to fire and the otherelements. My invention consists in compounding alum su ar of lead, andsilicate ofsodium,@ihcateot potassium, both, with or without dry wlnte21110 other ooloriifiatter, with wluc 1t wil unite or re purpose offorming a non-combustible or fireproof paint, according to the followingformula:

Dissolve equal amounts of aluurandsugar of leadin water, as much of eachas the waten will dissolve; then mix equal amounts of the solutionstogether in a separate vessel. After precipitation, mix the clear liquidwith hot sigeate of sodium in the proportion of about three parts of theaforesaid liquid, to four parts of the silicate of sodium. Afterward addcolorin matter, to suit, to the consistency of paint, Then it is readyto be applied in the manner of applying paint.

Instead of using silicate of sodium silicate gflyptassipm may be used,and it has been ound advantageous to mix them.

1 do not confine myself to t-lie'arbitrary proportions herein given, asthey may be varied to meet various conditions without departing from thesubstance of my invention; but

What- I do claim, and desire to secure by Letters Patent, is-

The composition fireproof paint consisting of alum, sugar of lead, and asilicate, compounded substantially as herein described.
